FilterStream DirtTamer ULTIMA V2510 Handheld Vacuum

At $70, FilterStream's DirtTamer ULTIMA V2510 was one of the most expensive units in our test, but was still among the worst performers. It left behind significant dirt and debris on bare floors and carpet and required extra strokes to remove pet hair. On the plus side, this handvac is easy to maneuver, has long battery and peak power runtimes, and comes with a HEPA filter, wetvac capability, and low battery indicator. filterstream.com.
